Malaysia's Sustainable Energy Development Authority (SEDA) is collaborating with CSIRO to investigate battery energy storage performance in hot and humid climates, particularly under Malaysia's tropical conditions. This study, supported by the Australian government's Partnerships for Infrastructure initiative, aims to address a knowledge gap in battery technology as most existing research pertains to cooler regions.

Malaysia targets a 70% renewable energy share by 2050, necessitating reliable energy storage solutions to manage solar generation intermittency and grid stability. The study reveals that while Malaysia's stable temperatures (22-32°C) are favorable, high humidity (80-90%) poses risks such as corrosion and thermal runaway.

The findings will inform policy frameworks, standards, and training for battery deployment in Malaysia, with potential for further research in Southeast Asia. This effort aligns with Malaysia's National Renewable Energy Policy updates and energy transition roadmap.
